SHADE-HOLDER ron LIGHTING-FIXTURES.

new. and useful Improvement in Shade-` Holders for Lighting-Fixtures, of whichthe following is the specification.

:The object of my invention is to provide a collapsible bowl holder. for lighting lixtures, which will be of great advantage for shipping purposes, and which can be readily and 'easily set up and adjusted for use by an inexperienced person, and when in operative position, will firmly and securely hold the bowl.

My invention consists of certain details of construction hereinafterset forth, pointed out in my claims and illustrated in the accompanying drawings, in which:

VFigure 1 shows a side elevation view of my bowl holder secured to a bowl, a part of the bowl being broken away.

Fig. 2 shows a sectional view of a portion of the socket, shell, ring, and a part of one of the arms I employ. e

Fig. 3 shows a side elevation view of the colla-r or ring I employ.

Fig. 4 sho-ws a detail view of the upper portion of one of the arms I employ.

Fig. 5 shows a detail view of a modified form of lmy device in which a shell is not employed, the light' socket performing the function of the shell. n

Referring to the accompanying drawings, the reference numeral 10 is used to indicate the cylindrical shell attached to the en d of an electric cord, chain hanger, or the like, said shell being slightly flared at its base, as shown at 11. This shell is designed to re# ceive an electric light socket 12, in the ordinary manner, so that Contact will be made to close the circuit which will thereafter be controlled by the light switch. The numeral 13 indicates a collar or ring, designed to engage the outer surface of the shell at the base, said ring being provided with a plun rality of channels or recesses 14 Vpressed outwardly from the inner surface of the ring, said recesses terminating, at the upper eX- tremity'of the shoulder 15. In the wall of the shoulder I provide orifices 16 whichare preferably T-shaped in conformation, located adjacent the upper extremity of the recessesin the said collar.

Specification of Letters Patent. Patented June 28, 1921 Application inea August '21, 1919. serial No. 318,850. i

The numerals 17 indicate arms preferably made of metal straps, their upper ends terminating inheads 18 with recesses thereunder, the construction being such that. the heads 18 are adapted to protrude through their respective T-shaped orifices in the collar, and to be secured thereiirby'means of the shoulders on the T-shaped recesses passying through the recesses below the heads on the endsV of vthe arms. The arms extend downwardly from the collar, and thence outs' wardly at substantially right angles, their outer ends terminating in hooked members 19 to receive the outer edge of the bowl 20. Immediately above the point where the arms fiare outwardly, as described, I have provided a slight outward and inward bend 21, and a spring metal ring 22 surrounds the plurality of arms r'above the bend in the vertical portions thereof, said ring being designed to spring over the bends in the arms, and tobe seated immediately above the outwardly flaring bends in the arms, when the arms have been secured to the bowl.

In practical operation, the collar with the arms loosely depending therefrom, is placed on the outer surface of the shell and moved y Adownwardly to its seat near the base thereof.

the shell. At this time the metal clamping ring is surrounding the depending arms above the bends in the vertical portions thereof. The bowl is then placed in position, being grasped by the hook'members on the outward ends of the arms, and the. clamped ring is Vthen forced downwardly over the outwardly and inwardly bending portions of the arms to its seat resting upon the substantially horizontal part of the arms, as shown in Fig. 1.. This firmly clamps the arms to the bowl.

It is obvious from this construction that the bowl will be firmly-and securely held in proper position by the arms and that my holder is collapsible so that it will occupy but small space for shipping purposes.

It is obvious that my device may be used on fixtures where asocket receiving shell is not employed, by causing the socket itself to perform the in Fig. 5, without varying my invention, the principal feature ofwhich is to provide a collar with loosely depending arms adapted function of thel shell as shown j tobe held in position by contact with the shell'or the outer surface of a socket shell, the outer ends. of the arms engaging the bowl, with means to hold the arms in position for such engagement.

Having-,thus described my invention, what I claim and desire to secure by Letters Patent of the United States, is: l. A bowl holder for lighting fixtures comprising in combination a collar adapted to itfover v'the' socketl receiving shell,I and channels in` the collar; a plurality-of-arms depending fro-nndand loosely securedwithin thefchannels in the coll-ar, said arms extending downwardly in av-substantially vertical plane and thenceoutwardly to the edge fof the bowl vand terminating in hooks to receive thebowl, an outwardly projecting shoulder formed in each arm above the point-where it flaresf'outwardly; a ring to encircle `the substantially vertical portions of the arms 'l said arms to secure the bowl thereto, a ring Y Y adapted to surround the arms .and tobe seated thereon sol as to retain the arms in rigid 'position with the bowl, whenlsecuredV thereto.

In testimony. whereof I have signedv the Y foregoing specification;
